feat: Add connect_with_defaults

[jalaziz]

Add connect_with_defaults function that intelligently selects the best connection method to use based on the DOCKER_HOST and DOCKER_TLS_VERIFY environment variables. This mimics the logic of the Docker CLI.

Fixes #310

I have not tested this yet. Hope to do that sometime this coming week.

Thanks for the contribution, I'm away from my computer for a week, but looking through the PR it looks good.

Maybe we can figure out how to test each branch somehow.

[jalaziz]

I think the best way to test the branches is to use the docker DinD image to launch different docker daemons and attempt to connect.

I'll try to set it up this weekend if I can find some time.

Adding tests in #373

[jalaziz]

Thank you and sorry for not getting to the tests myself 🙏🏼

Hate to be this person, but will there be a new release in the near future?

[fussybeaver]

Yeah, we're very close. My only reservation is that we now need to peg to a GitHub revision of the hyperlocal dependency.
